Re: [Bug-gnubg] Re: FIBS rating and error rates

[kvandoel]

Great Joern, thank you.

I have a suggestion:

It may  be interesting to users to  report loss of rating  points due to
move and cube  errors separately also, something like  (perhaps would be
cleaner to get rid of the () lines too as in the suggestion below?)

OVERALL

Luck based rating diff.     100
Error based rating          1234            1321
Chequer errors rating loss  616              629
Cube errors rating loss     200              100

One could also argue to put the  last 2 lines under the CHEQUER PLAY and
CUBE DECISIONS tab but IMO anyone interested in the rating estimate will
always also be interested in the  breakdown so it forces 2 clicks on the
user.

Best of all would be of course  to have a 5th "SUMMARY" tab which can be
populated as desired by the user.
